Cranial nerves and autonomic ganglia
Primary — twelve cranial nerves (sensory I/II/VIII, motor III/IV/VI/XI/XII, mixed V/VII/IX/X); trigeminal V1/V2/V3 (V3 motor mastication); IX afferent of gag, X efferent of gag and parasympathetic of heart/lungs/gut + RLN; XII tongue motor; cavernous sinus (III/IV/V1/V2/VI + carotid); sympathetic thoracolumbar T1-L2 paravertebral chain (stellate ganglion, Horner); parasympathetic craniosacral (III/VII/IX/X + S2-S4) terminal ganglia (ciliary/pterygopalatine/submandibular/otic); nicotinic/muscarinic and alpha/beta receptors.
